Eq5 goto , grind fix.

[cotterless45]

Last time out , the Dec axis decided to build up to a whirring followed by a grinding noise. I spent  some time removing everything down to the worm. The first thing that I spotted was that everything was covered in a tacky brown grease , yuk. Cleaned everything off and replaced with the Lithium grease.

I noticed (yikes !) that the spindle cog on the motor was just jarring against the mesh of the cogs. Took everything off , tried again. I noticed only one brass washer, there should be three ! Found two on the patio where they'd fallen out !

All assembled and adjusted , same problem as before. Went to the astronomy shed site. Thread on same problem. Blooming DIN cable. Swapped them over and worked perfectly.

The easiest solutions aren't the most obvious ! Nick.

No end to your talents !! I’d have bought a new mount ?

My manual pushing and shoving suits me fine ?

Thing is that spares , if needed are ouch ! Dec stepper eq5 SW motor ....£100, Dec Ra 8 pin DIN SW cable .....£20. Best look after the gear that you have . A good dab of grease goes a long way !

old Nick.

I stripped mine and regreased with lithium grease I suspect Damian may have reduced done it when he fixed it for me hopefully I never need a motor or both better getting second hand mount.
